\segno is an articulation?

[Dan Eble]

LilyPond currently has commands \segno, \coda, and \varcoda, which create 
articulations.  I'm looking for encouragement and approval to repurpose \segno 
and \coda as section delimiters.  If I don't get it, my new commands will have 
to be named something like \segnoSection and \codaSection.

To use \segno and \coda, I would have to rename the existing commands, but I'm 
not sure what would make the most sense.  \segnoArticulation, 
\codaArticulation, and \varcodaArticulation would get the job done, but the 
name of a technique would fit better with the rest of the articulations.  Do 
these symbols have standard meanings when used as articulations in some domain? 
 (I ask myself: In that case, why would they have their current names? but I 
hope...)
